| 阅读理解 |
| Tongue clicking is an important part of language for some southern African groups. And it could help disabled people control their wheelchairs. The key is a device that is put in the ears and listens for tongue clicks and then translates the sounds into commands for a wheelchair. Mouth interfaces (接口)that interact with wheelchairs are already common for seriously disabled people. One device that fits within the roof of the mouth houses buttons that can be pressed with the tongue. "But everything that involves tongue movement requires putting something in the mouth," says Ravi, from the University of Bristol, UK. Besides issues of hygiene (卫生),these devices make it difficult for the user to eat or speak, if they are able to ,while using it. Monitoring tongue movements through the ear avoids these problems. The new device, a simple microphone that looks like an earphone for listening to music, picks up certain sounds made by four sorts of tongue clicks. The microphone sends the information to a signal processor which sorts out the clicks and passes the information to the wheelchair, where each click type moves the chair in a distinct direction. Ravi's group has used the interface to control a virtual wheelchair. They have also used it to control the reaching and grasping movements of a robotic arm. The four tongue clicks can be mastered in a couple of hours, say the researchers. "This is a promising technique," says Jose del R. Millan, who has been working on brain interfaces for controlling wheelchairs at the Swiss Federal Institute of Technology in Lausanne. If it can be combined with real wheelchairs and shown to work reliably it could be very valuable for patients, he says. The researchers plan to start using real wheelchairs, but in the meantime they are looking at whether the number of commands can be increased by using a microphone in each ear, to get clearer signals to the wheelchairs. "Even if four clicks prove to be the limit, it only takes 0.2 second to detect each sound, so it's possible to spread high-level commands through combinations of clicking sounds," the researchers say. |

| Today, English is spoken in many countries.1English spoken in the UK is a little different from that in the USA in spelling, meaning, pronunciation, grammar, usage and so on. Sometimes,2English spoken in the UK is very different in every region (区域)3the country. Differences in spelling don't4speakers of British English from understanding the meanings of the words.5, they don't prevent speakers of American English from understanding the meanings either.6in spelling are not a big problem for even speakers of English as a7language. However, when different words in British English and American English are used to8the same thing 9the same word has different meanings in British English and American English, sometimes people will not be understood if they don't know common differences between British English and American English in meanings and usages. Sometimes even Americans and British people do not10each other because of different word meanings. 11, the British word "brolly" is an"umbrella" in America. And the British12potato chips "crisps". All of these differences led British writer George Bernard Shaw to13that Britain and America are two countries 14by the same language! That's the reason why confusion or misunderstanding will be caused in some situations. Of course, such confusion will15happen to speakers of English as a second language. | ||||
